' rTo all uhom it indy concern.' l

, United Stntesgresiding at Union city, in the county of Mason and State of `\\fashington, have invented cer- L tent as to insurethe removal of the most obstinate obtain new and useful Improvements in Stump-Fullers,

of which the following is a specification.

As is well known, great force is required for removing stumps of trees when clearing land.- This invention provides a mechanism whereby a comparatively small force is augmented, or increased to such an exstruction such as a stump or boulder.

The invention relatesto a train of gearing whereby effective leverage is manifolded, and a novel vframe- Work for the elements, whereby the strain is uniformly distributed, thereb) preventing concentrationl of the stress at any one point which would tend to result kdisastrously and shortenthe period of usefulness of the f appliance.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and Vaccompanying'drawinfrs. ,n n ,y

The frame-work of the.v device vcomprises a central member 1 which may be a plate, or bar, an upper member 2 and a.v low-er` member 3. The three bars 1, 2 and 3 have an approximate parallel arrangement, an end portion'of the upper member being downwardly deflected andvsecured an end portion of the central member 1, anda clevis 4l being' fitted to said members. The lower member 3 is se.

The gear wheel llhasa pinion 12 connectedtherewith by sleeve 13, the pinion l2 being in mesh with gear l wheel 14 loose on shaft 19 `connecting thethree'members 1, 2 and 3 of theframe-work. -A spool or drum r16, formed with, orconnected to, the gear wheel 14 so asV to rotate therewith, is arranged between the mem-v bers 1 and 2 andv is adapted to have the operating cable 17 wind thereon.

It is to be understood that the mechanism is to be of substantial structure and when arrangedffor use,

an anchoring cable 18 is attached to the yclevis 4 and is secured to one or more stems, or may be fast in any way to fix the position of the device while the same is in operation for removing the stump, or like obstruction, to f be displaced. After thel device has been firmly and securely anchored and the operating cable .17 has beenfhitched to the stump to be extracted,

A'power is yapplied to the sweep 7 and is transmitted from the shaft 6 to the spool, or drum, 16 through the intervention of they intermediate gearing herein reerred to. j l l f 'l It will be understood that the power applied to the sweep is augmented many times in its application to the spool, or drum 16; hence the great force Vexerted for winding the cable 17 upon said spool, or drum, is applied directly to the stump to be up-rootod and the displacement thereof is effected in a simple and convenient way as will be readily comprehendedl Having thusvdescribed thel invention, what is claimed as new is:

1. A stump puller comprising a frame-work embodyingv upper, lower und a central member, a power shaft mounted in the three members, a shaft connecting the three members nt lsome distance from said power shaft, a'spooi, or drum, mounted uponvsnid shaft and arranged between the uDner and centralmembersv ofv the frame-work, a

.geur wheel rotatable with said spool and located between the central and lower frame. members, an intermediate gearing between the power yshaft and said gearwheel for `transmitting motion to the latter, said gearing being nr ranged between the-'central and lower members of the frame-work. f l 2. A- stump puller comprising a frame-work embodying n. central and Vupper and lower members, the upper member having un end portion deflected toward. and secured to the central member, 'a power shaft mounted iu the three members of the frame-Work, spacing sleeves Vupon the powershait andar'ranged between the several members of the frame-work, the lnver spacingsleeve 'being fast to the power shaft and' provided with n pinion, n
